nucleotide substitution meaning in English
核苷酸置换
Examples
- Among the nucleotides substitution of cytb , transition is obviously higher than transversion
斑翅蝗cytb基因中核苷酸的替代转换明显高于颠换。 - 2 ) dna sequence variations were all nucleotide substitutions and neither insertions nor deletions were detected
2山na序列变异均为核耷酸替换，无插人和缺失突变。 - Approximately 7000 colonies were screened . one mutant was obtained , and its enzyme activity is 2 . 09 - fold higher than that of wild - type a - aldc in low temperature . the two nucleotide substitutions were occurred in the evolved a - aldc gene
根据定向进化的基本思想，我们利用易错pcr的方法，筛选了近7000个菌落，最终得到了一株在低温下也有较高酶活力的突变体。 - All the subjects were genotyped by pcr - rflp ( polymerase chain reaction - restriction fragment length polymorphism ) at polymorphic sac i site inside the exon 7 of the ahsg gene . this polymorphism involves a nucleotide substitution of c to g at the middle nucleotide of the codon at amino acid position 238 resulting in the replacement of threonine ( acc ) with serine ( agc )
所有的样本通过聚合酶链式反应?限制性片段长度多态性方法( pcr - rflp )对ahsg基因的第7个外显子内的sac多态性位点进行基因分型，该多态性位点为238号氨基酸密码子中间的碱基c到g的替换，使苏氨酸( thr ， acc )变为丝氨酸( ser ， agc ) 。
